Directors, secretaries and shareholders are not in CRO's open data. CRO sells officer information through CORE; it is not shown here rather than guessed.

Public contract awards

TED contract award notices (November 2023 onwards) and OGP / eTenders open data. Values are as published, not payments. A shared award names several suppliers, so its value is not theirs alone.
